System and method for implementing meeting moderator failover and failback

ABSTRACT

A method, apparatus, and computer-usable medium for scheduling a meeting, determining a set of policies for selecting a replacement meeting moderator if an original meeting moderator is not present in the meeting, specifying the a set of policies for reestablishing control of the meeting to the original meeting moderator when the original meeting moderator rejoins the meeting, deciding whether to implement a default policy or a custom policy as the set of policies. The default policy includes examining a user directory, establishing a hierarchy ranking of a collection of meeting members, where the original meeting moderator holds the highest rank, and designating a member of the collection of meeting members as a replacement meeting moderator, where the member holds a next highest rank in the hierarchy ranking.

BACKGROUND OF THE INVENTION

The present invention relates in general to the field of computers andsimilar technologies, and in particular to software utilized in thisfield.

Early computers were stand-alone units, which accessed and processedonly local databases using local computer programs. Today, however,modern computers are often networked, thus providing client computers ona network access to a variety of resources, including data, computerprograms, hardware devices (including storage drives and printers), etc.This resource availability is especially prevalent with the advent ofthe Internet, World Wide Web, private intranets and extranets, etc.,which provide access to web pages, databases, programs, and similarresources. Development of software for modem computers, once a taskperformed by a single programmer or a small group of programmers, is nowperformed by teams of developers and associated technical writers thatdocument the software.

Electronic meetings (e-meetings) are become a popular means ofcommunication in today's business world. Each e-meeting includes a“moderator” or “owner” who may delegate capabilities to other users.Those with skill in the art will appreciate that current e-meetingdesign and methodology creates several difficulties.

For example, if the moderator does not attend the e-meeting at thescheduled time, the e-meeting cannot proceed. Also, if the moderatorbecomes unavailable (e.g., network difficulties, hardware problems, orthe moderator is called to another meeting, etc.) before the moderatorcan delegate capabilities to other users, the e-meeting becomes stalled.If the e-meeting is scheduled by a system administrator whoinadvertently lists themselves as the moderator of the meeting, theintended moderator of the meeting cannot perform any actions within themeeting until the administrator changes the settings of the e-meeting.Also, if the original moderator delegates capabilities to another user,leaves the meeting, and subsequently returns, the new moderator mustmanually re-delegate the capabilities back to the original moderator.

Therefore, there is a need for a system and method of implementingmeeting moderator failback and failover to address the above mentionedlimitations of the prior art.

SUMMARY OF THE INVENTION

The present invention includes, but is not limited to, a method,apparatus, and computer-usable medium for scheduling a meeting, anddetermining a set of policies for selecting a replacement meetingmoderator if an original meeting moderator is not present in themeeting.

In one embodiment, the method includes the steps of specifying the a setof policies for reestablishing control of the meeting to the originalmeeting moderator when the original meeting moderator rejoins themeeting, deciding whether to implement a default policy or a custompolicy as the set of policies. The default policy includes examining auser directory, establishing a hierarchy ranking of a collection ofmeeting members, where the original meeting moderator holds the highestrank, and designating a member of the collection of meeting members as areplacement meeting moderator, where the member holds a next highestrank in the hierarchy ranking.

The above, as well as additional purposes, features, and advantages ofthe present invention will become apparent in the following detailedwritten description.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Referring now to the figures, and in particular, referring to FIG. 1there is illustrated an exemplary network in which a preferredembodiment of the present invention may be implemented. As depicted,network 100 includes clients 102 a-n, Internet 104, service providerserver 124, policy server 106, reservation server 112, meeting server116, and directory server 120.

Clients 102 a-n are implemented as computer systems (e.g., dataprocessing system 200 of FIG. 2) that are coupled to Internet 104 via amodem, network interface card (NIC), or any other type of networkinterface. In a preferred embodiment of the present invention, clients102 a-n are implemented as users of an electronic meeting system whereone of the clients 102 a-n is designated as a meeting moderator. Serviceprovider server 124 is coupled to Internet 104 and described herein inmore detail in conjunction with FIGS. 5 a-b, 6 a-c, 7 a-b, and 8 a-b.

Reservation server 112 includes memory 113, which further includesreservation program 114. Clients 102 a-n access reservation program 114to schedule electronic meetings and indicate whether default policy 108or custom policy 110 will be utilized during the electronic meeting.Users (e.g., one of clients 102 a-n) access reservation program 114 tospecify the time, location, number of participants, identity of theparticipants, and specify which failover and failback policy (stored inmemory 107 of policy server 106), if any, will be utilized during thee-meeting.

Policy server 106 includes memory 107, which further includes defaultpolicy 108 and custom policy 110, which are utilized to determine a newmeeting moderator in the event the originally designated meetingmoderator is unavailable.

In a preferred embodiment of the present invention, default policy 108may include a simple algorithm for designating a new meeting moderatorsuch as a default failover to the next person on a meeting attendeelist, or a more sophisticated algorithm where policy server 106 accessesmemory 121 of directory server 120, retrieves the listed position of allmeeting attendees, and designates the attendee with the next highestposition (e.g., assistant manager, etc.) as the new moderator. Assigninga meeting attendee with the next highest position as meeting moderatorallows the e-meeting to continue even if the originally designatedmoderator does not attend the meeting. Custom policy 110 is a failoverand failback policy that is specified by a user to apply to thespecifically scheduled meeting. For example, if a manager schedules ameeting utilizing reservation program 114, he may specify a specifichierarchy of meeting attendees that may be designated as meetingmoderator (e.g., assistant manager, shift manager, etc.)

Meeting server 116 includes memory 117, which further includeselectronic meeting (e-meeting) program 118. At the meeting timescheduled with reservation program 114, clients 102 a-n log on toe-meeting program 118 to hold a meeting. Directory server 120 includesmemory 121, which further includes user directory 122. User directory122 is a database containing information (e.g., position, contact, andlocation, etc.) regarding registered users of e-meeting program 118.

Those skilled in the art will appreciate that network 100 can includemany additional components (e.g., routers, firewalls, etc.) notspecifically illustrated in FIG. 1. Because such additional componentsare not necessary for an understanding of the present invention, theyare not illustrated in FIG. 1 or discussed further herein.

FIG. 2 is a block diagram illustrating an exemplary data processingsystem 200 in which a preferred embodiment of the present invention maybe implemented. Those with skill in the art will appreciate that dataprocessing system 200 may be utilized to implement both clients 102 a-nand servers 106, 112, 116, 120, and 124. As depicted, exemplary dataprocessing system 200 includes processing unit(s) 202, shown asprocessing units 202a and 202b in FIG. 1, which are coupled to systemmemory 204 via system bus 206. Preferably, system memory 204 may beimplemented as a collection of dynamic random access memory (DRAM)modules. Typically, system memory 204 includes data and instructions forrunning a collection of applications. Mezzanine bus 208 acts as anintermediary between system bus 206 and peripheral bus 214. Those withskill in this art will appreciate that peripheral bus 214 may beimplemented as a peripheral component interconnect (PCI), acceleratedgraphics port (AGP), or any other peripheral bus. Coupled to peripheralbus 214 is hard disk drive 210, which is utilized by data processingsystem 200 as a mass storage device. Also coupled to peripheral bus 214is a collection of peripherals 212 a-n.

FIG. 3 is a block diagram illustrating exemplary contents of systemmemory 204 of clients 102 a-n, according to a preferred embodiment ofthe present invention. As illustrated, system memory 204 includesoperating system 302, which further includes shell 304 for providingtransparent user access to resources such as application programs 316.Generally, shell 304 is a program that provides an interpreter and aninterface between the user and the operating system. More specifically,shell 304 executes commands that are entered into a command line userinterface or a file. Thus, shell 304 (as it is called in UNIX®), alsocalled a command processor in Windows®, is generally the highest levelof the operating system software hierarchy and servers as a commandinterpreter. The shell provides a system prompt, interprets commandsentered by keyboard, mouse, or other user input media, and sends theinterpreted command(s) to the appropriate lower levels of the operatingsystem (e.g., kernel 306) for processing. Note that while shell 304 is atext-based, line-oriented user interface, the present invention willsupport other user interface modes, such as graphical, voice, gestural,etc. equally well.

As illustrated, operating system 302 also includes kernel 306, whichincludes lower levels of functionality for operating system 302,including providing essential services required by other parts ofoperating system 302 and application programs 316, including memorymanagement, process and task management, disk management, and mouse andkeyboard management. Application programs 316 can include a browser 318,utilized for access to Internet 104, e-meeting interface 320, wordprocessors, spreadsheets, and other application programs 322.

FIG. 4 is a high-level logical flowchart diagram illustrating anexemplary method of implementing meeting moderator failover and failbackaccording to a preferred embodiment of the present invention. Theprocess begins at step 400 and proceeds to step 402, which illustratesone of clients 102 a-n (e.g., client 102 a) scheduling an electronicmeeting (e-meeting) by logging on to registration server 112 andaccessing registration program 114. Client 102 a determines whether ornot the scheduled e-meeting will take advantage of a failover andfailback policy (step 404). If client 102a determines that the schedulede-meeting will not utilize a failover and failback policy, the processcontinues to step 406, which illustrates the process ending.

If client 102 a determines that the scheduled e-meeting will utilize afailover and failback policy, the process continues to step 408, whichdepicts client 102 a determining if the scheduled e-meeting will utilizea default or customized failover and failback policy. The determinationis then indicated in reservation program 114 (steps 410 or 412), and theprocess proceeds to step 413.

Step 413 illustrates clients 102 a-n logging on to e-meeting program 118stored in memory 117 of meeting server 116 via e-meeting interface 320to begin the e-meeting. For the purposes of discussion, assume thatclient 102 a is the originally designated meeting moderator. If a newmeeting moderator is required (e.g., client 102 a has left the e-meetingor did not show up at the start of the meeting), the selected failoverpolicy (default policy 108 or custom policy 110) is utilized and a newmeeting moderator is selected (steps 414 and 416). If a new meetingmoderator is not required, the process proceeds to step 418, whichillustrates a determination made by meeting server 116 as to whether thee-meeting has ended. If the e-meeting has not ended, the process returnsto step 414 and proceeds in an iterative fashion. If the e-meeting hasended, the process continues to step 420, which depicts the processending.

The present invention includes, but is not limited to, a method,apparatus, and computer-usable medium for scheduling a meeting,determining a set of policies for selecting a replacement meetingmoderator if an original meeting moderator is not present in themeeting, specifying the a set of policies for reestablishing control ofthe meeting to the original meeting moderator when the original meetingmoderator rejoins the meeting, deciding whether to implement a defaultpolicy or a custom policy as the set of policies. The default policyincludes examining a user directory, establishing a hierarchy ranking ofa collection of meeting members, where the original meeting moderatorholds the highest rank, and designating a member of the collection ofmeeting members as a replacement meeting moderator, where the memberholds a next highest rank in the hierarchy ranking.

It should be understood that at least some aspects of the presentinvention may alternatively be implemented in a computer-useable mediumthat contains a program product. Programs defining functions on thepresent invention can be delivered to a data storage system or acomputer system via a variety of signal-bearing media, which include,without limitation, non-writable storage media (e.g., CD-ROM), writablestorage media (e.g., hard disk drive, read/write CD ROM, optical media),system memory such as but not limited to Random Access Memory (RAM), andcommunication media, such as computer and telephone networks includingEthernet, the Internet, wireless networks, and like network systems. Itshould be understood, therefore, that such signal-bearing media whencarrying or encoding computer readable instructions that direct methodfunctions in the present invention, represent alternative embodiments ofthe present invention. Further, it is understood that the presentinvention may be implemented by a system having means in the form ofhardware, software, or a combination of software and hardware asdescribed herein or their equivalent.

Software Deployment

Thus, the method described herein, and in particular as shown anddescribed in FIG. 4, can be deployed as a process software from serviceprovider server 124 to client computers (policy server 106, reservationserver 112, meeting server 116, and directory server 120).

Referring then to FIG. 5, step 500 begins the deployment of the processsoftware. The first thing is to determine if there are any programs thatwill reside on a server or servers when the process software is executed(query block 502). If this is the case, then the servers that willcontain the executables are identified (block 504). The process softwarefor the server or servers is transferred directly to the servers'storage via File Transfer Protocol (FTP) or some other protocol or bycopying though the use of a shared file system (block 506). The processsoftware is then installed on the servers (block 508).

Next, a determination is made on whether the process software is to bedeployed by having users access the process software on a server orservers (query block 510). If the users are to access the processsoftware on servers, then the server addresses that will store theprocess software are identified (block 512).

A determination is made if a proxy server is to be built (query block514) to store the process software. A proxy server is a server that sitsbetween a client application, such as a Web browser, and a real server.It intercepts all requests to the real server to see if it can fulfillthe requests itself. If not, it forwards the request to the real server.The two primary benefits of a proxy server are to improve performanceand to filter requests. If a proxy server is required, then the proxyserver is installed (block 516). The process software is sent to theservers either via a protocol such as FTP or it is copied directly fromthe source files to the server files via file sharing (block 518).Another embodiment would be to send a transaction to the servers thatcontained the process software and have the server process thetransaction, then receive and copy the process software to the server'sfile system. Once the process software is stored at the servers, theusers, via their client computers, then access the process software onthe servers and copy to their client computers file systems (block 520).Another embodiment is to have the servers automatically copy the processsoftware to each client and then run the installation program for theprocess software at each client computer. The user executes the programthat installs the process software on his client computer (block 522)then exits the process (terminator block 524).

In query step 526, a determination is made whether the process softwareis to be deployed by sending the process software to users via e-mail.The set of users where the process software will be deployed areidentified together with the addresses of the user client computers(block 528). The process software is sent via e-mail to each of theusers' client computers (block 530). The users then receive the e-mail(block 532) and then detach the process software from the e-mail to adirectory on their client computers (block 534). The user executes theprogram that installs the process software on his client computer (block522) then exits the process (terminator block 524).

Lastly a determination is made on whether to the process software willbe sent directly to user directories on their client computers (queryblock 536). If so, the user directories are identified (block 538). Theprocess software is transferred directly to the user's client computerdirectory (block 540). This can be done in several ways such as, but notlimited to, sharing of the file system directories and then copying fromthe sender's file system to the recipient user's file system oralternatively using a transfer protocol such as File Transfer Protocol(FTP). The users access the directories on their client file systems inpreparation for installing the process software (block 542). The userexecutes the program that installs the process software on his clientcomputer (block 522) and then exits the process (terminator block 524).

VPN Deployment

The present software can be deployed to third parties as part of aservice wherein a third party VPN service is offered as a securedeployment vehicle or wherein a VPN is built on-demand as required for aspecific deployment.

A virtual private network (VPN) is any combination of technologies thatcan be used to secure a connection through an otherwise unsecured oruntrusted network. VPNs improve security and reduce operational costs.The VPN makes use of a public network, usually the Internet, to connectremote sites or users together. Instead of using a dedicated, real-worldconnection such as leased line, the VPN uses “virtual” connectionsrouted through the Internet from the company's private network to theremote site or employee. Access to the software via a VPN can beprovided as a service by specifically constructing the VPN for purposesof delivery or execution of the process software (i.e. the softwareresides elsewhere) wherein the lifetime of the VPN is limited to a givenperiod of time or a given number of deployments based on an amount paid.

The process software may be deployed, accessed and executed througheither a remote-access or a site-to-site VPN. When using theremote-access VPNs the process software is deployed, accessed andexecuted via the secure, encrypted connections between a company'sprivate network and remote users through a third-party service provider.The enterprise service provider (ESP) sets a network access server (NAS)and provides the remote users with desktop client software for theircomputers. The telecommuters can then dial a toll-bee number or attachdirectly via a cable or DSL modem to reach the NAS and use their VPNclient software to access the corporate network and to access, downloadand execute the process software.

When using the site-to-site VPN, the process software is deployed,accessed and executed through the use of dedicated equipment andlarge-scale encryption that are used to connect a company's multiplefixed sites over a public network such as the Internet.

The process software is transported over the VPN via tunneling which isthe process of placing an entire packet within another packet andsending it over a network. The protocol of the outer packet isunderstood by the network and both points, called tunnel interfaces,where the packet enters and exits the network.

The process for such VPN deployment is described in FIG. 6. Initiatorblock 602 begins the Virtual Private Network (VPN) process. Adetermination is made to see if a VPN for remote access is required(query block 604). If it is not required, then proceed to query block606. If it is required, then determine if the remote access VPN exists(query block 608).

If a VPN does exist, then proceed to block 610. Otherwise identify athird party provider that will provide the secure, encrypted connectionsbetween the company's private network and the company's remote users(block 612). The company's remote users are identified (block 614). Thethird party provider then sets up a network access server (NAS) (block616) that allows the remote users to dial a toll free number or attachdirectly via a broadband modem to access, download and install thedesktop client software for the remote-access VPN (block 618).

After the remote access VPN has been built or if it has been previouslyinstalled, the remote users can access the process software by dialinginto the NAS or attaching directly via a cable or DSL modem into the NAS(block 610). This allows entry into the corporate network where theprocess software is accessed (block 620). The process software istransported to the remote user's desktop over the network via tunneling.That is, the process software is divided into packets and each packetincluding the data and protocol is placed within another packet (block622). When the process software arrives at the remote user's desktop, itis removed from the packets, reconstituted and then is executed on theremote user's desktop (block 624).

A determination is then made to see if a VPN for site to site access isrequired (query block 606). If it is not required, then proceed to exitthe process (terminator block 626). Otherwise, determine if the site tosite VPN exists (query block 628). If it does exist, then proceed toblock 630. Otherwise, install the dedicated equipment required toestablish a site to site VPN (block 638). Then build the large scaleencryption into the VPN (block 640).

After the site to site VPN has been built or if it had been previouslyestablished, the users access the process software via the VPN (block630). The process software is transported to the site users over thenetwork via tunneling (block 632). That is the process software isdivided into packets and each packet including the data and protocol isplaced within another packet (block 634). When the process softwarearrives at the remote user's desktop, it is removed from the packets,reconstituted and is executed on the site user's desktop (block 636).The process then ends at terminator block 626.

Software Integration

The process software which consists of code for implementing the processdescribed herein may be integrated into a client, server and networkenvironment by providing for the process software to coexist withapplications, operating systems and network operating systems softwareand then installing the process software on the clients and servers inthe environment where the process software will function.

The first step is to identify any software on the clients and serversincluding the network operating system where the process software willbe deployed that are required by the process software or that work inconjunction with the process software. This includes the networkoperating system that is software that enhances a basic operating systemby adding networking features.

Next, the software applications and version numbers will be identifiedand compared to the list of software applications and version numbersthat have been tested to work with the process software. Those softwareapplications that are missing or that do not match the correct versionwill be upgraded with the correct version numbers. Program instructionsthat pass parameters from the process software to the softwareapplications will be checked to ensure the parameter lists matches theparameter lists required by the process software. Conversely parameterspassed by the software applications to the process software will bechecked to ensure the parameters match the parameters required by theprocess software. The client and server operating systems including thenetwork operating systems will be identified and compared to the list ofoperating systems, version numbers and network software that have beentested to work with the process software. Those operating systems,version numbers and network software that do not match the list oftested operating systems and version numbers will be upgraded on theclients and servers to the required level.

After ensuring that the software, where the process software is to bedeployed, is at the correct version level that has been tested to workwith the process software, the integration is completed by installingthe process software on the clients and servers.

For a high-level description of this process, reference is now made toFIG. 7. Initiator block 702 begins the integration of the processsoftware. The first tiling is to determine if there are any processsoftware programs that will execute on a server or servers (block 704).If this is not the case, then integration proceeds to query block 706.If this is the case, then the server addresses are identified (block708). The servers are checked to see if they contain software thatincludes the operating system (OS), applications, and network operatingsystems (NOS), together with their version numbers, which have beentested with the process software (block 710). The servers are alsochecked to determine if there is any missing software that is requiredby the process software in block 710.

A determination is made if the version numbers match the version numbersof OS, applications and NOS that have been tested with the processsoftware (block 712). If all of the versions match and there is nomissing required software the integration continues in query block 706.

If one or more of the version numbers do not match, then the unmatchedversions are updated on the server or servers with the correct versions(block 714). Additionally, if there is missing required software, thenit is updated on the server or servers in the step shown in block 714.The server integration is completed by installing the process software(block 716).

The step shown in query block 706, which follows either the steps shownin block 704, 712 or 716 determines if there are any programs of theprocess software that will execute on the clients. If no processsoftware programs execute on the clients the integration proceeds toterminator block 718 and exits. If this not the case, then the clientaddresses are identified as shown in block 720.

The clients are checked to see if they contain software that includesthe operating system (OS), applications, and network operating systems(NOS), together with their version numbers, which have been tested withthe process software (block 722). The clients are also checked todetermine if there is any missing software that is required by theprocess software in the step described by block 722.

A determination is made is the version numbers match the version numbersof OS, applications and NOS that have been tested with the processsoftware (query block 724). If all of the versions match and there is nomissing required software, then the integration proceeds to terminatorblock 718 and exits.

If one or more of the version numbers do not match, then the unmatchedversions are updated on the clients with the correct versions (block726). In addition, if there is missing required software then it isupdated on the clients (also block 726). The client integration iscompleted by installing the process software on the clients (block 728).The integration proceeds to terminator block 718 and exits.

On Demand

The process software is shared, simultaneously serving multiplecustomers in a flexible, automated fashion. It is standardized,requiring little customization and it is scalable, providing capacity ondemand in a pay-as-you-go model.

The process software can be stored on a shared file system accessiblefrom one or more servers. The process software is executed viatransactions that contain data and server processing requests that useCPU units on the accessed server. CPU units are units of time such asminutes, seconds, hours on the central processor of the server.Additionally the assessed server may make requests of other servers thatrequire CPU units. CPU units are an example that represents but onemeasurement of use. Other measurements of use include but are notlimited to network bandwidth, memory usage, storage usage, packettransfers, complete transactions etc.

When multiple customers use the same process software application, theirtransactions are differentiated by the parameters included in thetransactions that identify the unique customer and the type of servicefor that customer. All of the CPU units and other measurements of usethat are used for the services for each customer are recorded. When thenumber of transactions to any one server reaches a number that begins toaffect the performance of that server, other servers are accessed toincrease the capacity and to share the workload. Likewise when othermeasurements of use such as network bandwidth, memory usage, storageusage, etc. approach a capacity so as to affect performance, additionalnetwork bandwidth, memory usage, storage etc. are added to share theworkload.

The measurements of use used for each service and customer are sent to acollecting server that sums the measurements of use for each customerfor each service that was processed anywhere in the network of serversthat provide the shared execution of the process software. The summedmeasurements of use units are periodically multiplied by unit costs andthe resulting total process software application service costs arealternatively sent to the customer and or indicated on a web siteaccessed by the customer which then remits payment to the serviceprovider.

In another embodiment, the service provider requests payment directlyfrom a customer account at a banking or financial institution.

In another embodiment, if the service provider is also a customer of thecustomer that uses the process software application, the payment owed tothe service provider is reconciled to the payment owed by the serviceprovider to minimize the transfer of payments.

With reference now to FIG. 8, initiator block 802 begins the On Demandprocess. A transaction is created than contains the unique customeridentification, the requested service type and any service parametersthat further, specify the type of service (block 804). The transactionis then sent to the main server (block 806). In an On Demand environmentthe main server can initially be the only server, then as capacity isconsumed other servers are added to the On Demand environment.

The server central processing unit (CPU) capacities in the On Demandenvironment are queried (block 808). The CPU requirement of thetransaction is estimated, then the servers available CPU capacity in theOn Demand environment are compared to the transaction CPU requirement tosee if there is sufficient CPU available capacity in any server toprocess the transaction (query block 810). If there is not sufficientserver CPU available capacity, then additional server CPU capacity isallocated to process the transaction (block 812). If there was alreadysufficient available CPU capacity then the transaction is sent to aselected server (block 814).

Before executing the transaction, a check is made of the remaining OnDemand environment to determine if the environment has sufficientavailable capacity for processing the transaction. This environmentcapacity consists of such things as but not limited to networkbandwidth, processor memory, storage etc. (block 816). If there is notsufficient available capacity, then capacity will be added to the OnDemand environment (block 818). Next the required software to processthe transaction is accessed, loaded into memory, then the transaction isexecuted (block 820).

The usage measurements are recorded (block 822). The usage measurementsconsist of the portions of those functions in the On Demand environmentthat are used to process the transaction. The usage of such functionsas, but not limited to, network bandwidth, processor memory, storage andCPU cycles are what is recorded. The usage measurements are summed,multiplied by unit costs and then recorded as a charge to the requestingcustomer (block 824).

If the customer has requested that the On Demand costs be posted to aweb site (query block 826), then they are posted (block 828). If thecustomer has requested that the On Demand costs be sent via e-mail to acustomer address (query block 830), then these costs are sent to thecustomer (block 832). If the customer has requested that the On Demandcosts be paid directly from a customer account (query block 834), thenpayment is received directly from the customer account (block 836).
